What antidepressant helped your dissociation? Dealing with blank mind, anhedonia, and depression after ketamine use

I’m really struggling and would deeply appreciate any help or insight. It’s been 3 months since I used ketamine, and since then I’ve felt completely disconnected from myself. I’m stuck in a constant state of dissociation, blank mind, deep anhedonia, and depression. I’ve lost all sense of personality—just feel like an empty shell—and my cognitive function is so impaired it’s hard to even think clearly or hold conversations.

Every single day feels the same. There’s no progress, no variation, just a flat existence. I’ve tried everything I could think of—exercise, supplements, microdosing, even a few full psilocybin trips—but nothing has helped.

I honestly see no way out of this naturally anymore, and I’m wondering if anyone here found an antidepressant (or any treatment) that helped pull them out of something similar. I know everyone’s different, but even hearing about what worked for someone else might give me a thread of hope.

Thank you so much in advance.
